Normality is a sweet and nice character piece for Clara, giving us a glimpse into her early teaching days at Coal Hill while she's still with Eleven. We have part adventure in space and then part normal school day with some meaningful reflection on life and purpose. One of the better short stories collected here.

Clara having a fear of heights feels a bit out of nowhere, don't think it's mentioned in her TV stories (though I could be misremembering).

Other than that weird point though, this characterisation for Clara is great, it's really a shame we dont' see more of Teacher Clara, especially towards the start of her teaching tenure, most of what we do see is from when she's already well settled into it.

Seeing how she views the kids is great, she really enjoys teaching and sees something in these kids that she wouldn't've without The Doctor. It's just really sweet, and the kind of thing that really works in this collection of kids stories.
